Brazilian researchers have developed a low-cost, portable biosensor that can quickly identify a protein whose altered levels are associated with psychiatric disorders, such as depression, schizophrenia, and bipolar disorder. When it becomes commercially available in the future, it may contribute to early detection, which is essential for treating and monitoring patients' clinical conditions. The biosensor is the result of a partnership between researchers at the University of São [...]

The Lear's macaw (Anodorhynchus leari), a species endemic to the north of the state of Bahia, Brazil, nearly went extinct in the 1990s. Thanks to conservation efforts, its population has grown to 2,500 today. However, this expansion has coincided with the rapid growth of the region's power grid, which increased by approximately 30% between 2018 and 2023. Consequently, between January and August of 2025, 35 macaws were found dead with signs of electrocution — accidental death or [...]

in the journal ACS Sustainable Chemistry and Engineering and featured on its cover showed that a fraction obtained from lignin, an organic polymer responsible for the rigidity of plant cell walls, was able to improve the performance of nanoparticles with herbicide. The study was conducted by researchers from three research institutions in the state of São Paulo, Brazil: São Paulo State University (UNESP), the State University of Campinas (UNICAMP), and the Federal University of [...]

A vaccine trial against elephant endotheliotropic herpesvirus (EEHV) — a leading cause of death in young Asian elephants — has proved the vaccine is safe and triggers a strong virus-fighting immune response, according to an international team led by the University of Surrey, Chester Zoo, and the Animal and Plant Health Agency (APHA). With the ability to kill elephants in just 24 hours, EEHV poses a severe threat to the survival of Asian elephants — a species already listed as [...]

Hydrothermal vents may have triggered early molecular chemistry on ancient Earth   by Staff Writers for ACS News A study published in the Journal of the American Chemical Society recreated in the laboratory chemical reactions that may have occurred on Earth about 4 billion years ago, producing the first molecular precursors for the emergence of life. The experiment showed that, without the presence of enzymes, natural gradients of pH, redox potential, and temperature present in [...]

Amid the preparatory discussions for COP30, which also involve health-related topics, a study contributes to our understanding of the relationship between deforestation and the spread of malaria in the Legal Amazon. This region encompasses all nine Brazilian states in which the Amazon biome is found and was established by the federal government for regional development purposes. The study shows that intermediate forest cover with 50% deforestation increases human cases of the disease and [...]

Sixty-six million years ago, two genera of long-necked, quadrupedal dinosaurs had an advantage over other sauropods: they could easily stand on their hind legs for extended periods. This allowed them to scare off potential predators and feed on leaves high up in trees, for example. The Brazilian Uberabatitan and the Argentine Neuquensaurus were about the size of a modern elephant. Although they were considered small for their group, it is estimated that adult Uberabatitans could reach 26 [...]

Some ancient stony corals were able to survive extreme environmental changes, which suggests that some modern species could possess some resilience to the effects of climate change, according to research in Nature. Stony corals are crucial to the framework of many marine ecosystems but have come under threat in recent years from changes to their environments due to global climate change. Understanding the history of these species and how they withstood previous long-term shifts in [...]
